Breaking news from Pakistan: Former Prime Minister Benazir Bhutto was assassinated after giving a speech to supporters. The killer shot at her car, then used a suicide bomb, killing himself and at least 22 others in the blast.

Bhutto recently returned to Pakistan from her 8-year exile in Great Britain to garner support for creating democracy in the country. She has risked her life in the past while speaking out against the Musharraf government, narrowly escaping other suicide bombings. Bhutto had filed her nomination for a seat in the Parliament in November.

Riots are already breaking out in Pakistan, and the country is likely to see even more turmoil in the weeks to come because of the assassination.
